Okay, top of my list. I've never watched the show, don't even know the characters name. But just going from the endless ads on USA, it would have to be the lead character in The Starter Wife. All that mugging for the camera and 'wackiness' just makes me wanna choke a bitch.
You stopped watching after the first episode?
I sure as hell did.
Well ya got me beat. I only just made it through the pilot before deciding I hated every single character.
Several companions of the Doctor have already been mentioned and I must admit I'm not far enough in my watching Classic Who to comment on them but I have to mention the Doctor's first companion here, his granddaughter Susan.
She used to bug me. Then I watched later episodes featuring the Time Lords and realized that most Gallifreyans are bloody useless outside their domed cities.
Welp, time to go on a Trek rant.
I didn't mind Wesley all that much once Roddenberry departed and they stopped with the 'Wesley saves the day' stories.
Neelix. The eternal perkiness just got on my damn nerves. Plus God help me, whenever I look at his head all I can think about is some bizarre variety of Fall squash.
Quark I could tolerate. But every time the damn Grand Nagus story rolled around I just wanted to hurt someone.
And speaking of the urge to kill. Troi's mother.
And any female added to a Trek show in order to 'sex things up'. You all know who I mean.
